Title: Controlling method for recorder by signal from broadcasting station
Inventor: TOKUDA TAKESHI
IPC: G11B15/02
Filed: 1980-12-05
Abstract: PURPOSE:To record only music except conversation, etc., by sending specific signals immediately before and after a transmitted music broadcast, and by controlling a reception-side recorder by those signals. CONSTITUTION:When a transmission side is to send music, a specific signal is sent immediately before it and once it is confirmed by a reception side recorder, a recording pause state is released to start recording. At the transmission side, another specific signal is sent once the music ends, and the recorder returns to the pause state by the signal. The signals are given frequencies where human's ears do not sense the signals, so that people who listen to a broadcast normally are not influenced by the signals at all. Consequently, a tape on which only music is recorded is obtained even if a listener is absent.

Title: Reset circuit
Inventor: TANAGAWA KOJI
IPC: G01R19/165
Filed: 1986-07-21
Abstract: PURPOSE:To prevent the unstable operation of a logic circuit due to the fluctuation of power supply, to reduce the cost of the device using the titled circuit and also the space by providing a MOS transistor (TR) detecting the power voltage and a FF holding its detected output. CONSTITUTION:If the power voltage is decreased more than a prescribed value during the operation of a logic circuit 1, the MOS 12 is turned on and a voltage is produced across a resistor 13. The said voltage sets a FF 15, an output terminal Q goes to an H level and a reset output RO resets the circuit 1. Since the state is stored in the FF 15, even when the power voltage restores to a normal value, the circuit 1 remains to be reset. Thus, even if the power voltage repeats the state of decrease/normal value for many times, the circuit 1 remains unchanged (reset) and no unstable operation is caused. In bringing the reset input RI to an L level next, the FF 15 is reset. When the input RI restores to the H level, the output of an inverter 16 goes to an L level and also the output RO goes to the L level, then the reset state of the circuit 1 is released to restart the normal operation.

Title: Display device
Inventor: WASHIMI SATOSHI
IPC: G09F9/30
Filed: 1985-08-05
Abstract: PURPOSE:To obtain a display device having high luminance and high contrast by periodically changing the refractive index in the optional part of an optical waveguide constituted of an electrooptic member by electrodes formed to a stripe shape so that propagated light is diffracted. CONSTITUTION:The optical waveguide 1 is formed of the electroptic material of which the refractive index changes when an electric field is impressed thereto, for example, lithium niobate. An electric field is generated in the region where the stripe electrodes 4 and a transparent electrode face each other by the voltage from an electric field control device 6 when the output is produced from said device. The refractive index in then changed by an electrooptic effect between the opposed positions in the optical waveguide 1. Since the electrodes 4 are formed to the stripe shape, the periodic refractive index change is given to the optical waveguide with regard to the advancing direction of propagated light. This change corresponds equivalently to a diffraction grating. Accordingly, the propagated light 7 successively receives the diffraction and emerges and leaks to the outside by failing to make total reflection at the boundary face between the waveguide 1 and clad 3.
